I cannot really determine if I am having some sort of hardware issue with the uarm swift.
Here is the arm, started up from default, rotated with G2202 N3 V45
and right after that sent the G2202 N3 V135 command. BTW, this is how
the suction cup rotates anyway, it’s not these particular two angles:
OK, so, someone looking at this might say “Something wrong with the
servo”. But when you reset the arm, the suction cup returns to zero
pretty quickly. Here it is:
In this video: I have started up the arm, rotated to G2202 N3 V45 and
once that finished, simply disconnect from the arm. Here, it is also
visible what I mention in another post, for some reason the arm jams
itself in that position.
Anyway, the point here is that just before the arm resets itself, the suction cup rotates to its zero position pretty quickly.
I am not sure if this is a problem with the servo or the feedback from the servo or a matter of a parameter.
I am more inclined to fix this myself instead of shipping the arm
back to uFactory. As long as I can get some help on what the key issue
might be. First thing I would do would be to check if there is any
constriction, anything that may have been over tightened. If that turns
out to be ok I am going to remove the servo and check it on its own. If
there are any problems with the servo itself, I could try replacing it.
Not sure if it is a special grade servo or if one can be shipped from
All the best
